We divide 485270 by 28
We want to figure out the number of times 485270 can be divided by 28.

On to step 1:
4 divided by 28 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 28

Let's proceed to step 2:
28 can be fit into 48 1 times, resulting in a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 28 from 48, we get 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 28

On to step 3:
28 goes into 205 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 9 after subtracting 196 from 205.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 28

Advancing to step 4:
28 goes into 92 3 times with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 173.0
If we take 84 away from 92, we end up with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 28

Let's proceed to step 5:
28 goes into 87 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 1733.0
Subtract 84 from 87 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 28

Let's proceed to step 6:
28 can be fit into 30 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 17331.0
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
28 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 17331.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 17331.07
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
When dividing 40 by 28, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 17331.071
Subtracting 28 from 40 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
When dividing 120 by 28, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 17331.0714
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
If we divide 80 by 28, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 17331.07142
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
28 can be fit into 240 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 17331.071428
If we take 224 away from 240, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
28 can be fit into 160 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 17331.0714285
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 17331.07142857
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 17331.07142857 with a remainder of 4e-09.
